bone?Of course mammals have a back bone or spine. That is one of the features that separates mammals from other animals. We are mammals as well. Place your hand on your back. What do you feel? That's your spine. Dogs, cats, horses, and even fish have spines. There are two groups of animals. The vertebrae and the invertebrate. We are vertebrae because we have spines. Insects are invertebrates because they have what is called an exoskeleton. Their skeleton is on the outside of their bodies instead of the inside.
Bone structure vary enormously in mammals. If you compare the bone structures of a mouse, a giraffe, a whale, and a bat (all of which are mammals) you will find tremendous differences.

Any invertebrate. They have no bones at all.
All vertebrates have bones - this includes mammals, birds, reptiles, amphibians and fish. Sharks, rays and skates are an exception - they have cartilage in place of bones, but the cartilage provides the same function as a bony skeleton. However, there are millions of species of animals that do not have bones - all the invertebrates. This includes crustaceans (lobster, crayfish, shrimp, etc.), molluscs (snails, octopi, clams, etc.), insects, echinoderms (sea urchins, etc.) and a variety of other animals.
-Backbone, ribs, skull, pelvis... the list goes on and on.
Depends on the animal- there is no one answer. Unless you want to say that ALL bones are in animals.
because they have evolved from an animal with a much shorter neck called climacoceras, the bones has just been elongated. Al mamals have the same skeleton, but the bones have changed.
To determine whether an animal is a vertebrate or invertebrate, ask yourself whether it has any bones. Zebras have bones, and all animals that have bones are vertebrates. So zebras are vertebrates. Any animal without bones is an invertebrate.
It depends on what animal you are talking about, Jellyfish dont have bones, but if you are talking about a mammal, Yes.
